Are scrollbars on frames doable? #27
Description
Working off of Bryan Oakley's TKinter example here: https://stackoverflow.com/questions/3085696/adding-a-scrollbar-to-a-group-of-widgets-in-tkinter/3092341#3092341 I only got this far:
`
func NewWindow() *Window {
mw := &Window{tk.RootWindow()}
mw.ResizeN(800, 600)
canvas := tk.NewCanvas(mw, tk.WidgetAttrWidth(800), tk.WidgetAttrHeight(600), tk.CanvasAttrBorderWidth(0), tk.CanvasAttrBackground("white"))
frame := tk.NewFrame(canvas, tk.WidgetAttrWidth(750), tk.WidgetAttrHeight(270), tk.WidgetAttrInitUseTheme(false))
frame.SetNativeAttribute("background", "black")
// populate with some labels
for i := 0; i < 40; i++ {
lbl := tk.NewLabel(frame, "label "+strconv.Itoa(i))
lbl.SetBackground("#ccc")
tk.Grid(lbl, tk.GridAttrRow(i), tk.GridAttrColumn(0), tk.GridAttrPadx(5), tk.GridAttrPady(5), tk.GridAttrSticky(tk.StickyAll))
}
vertScrollbar := tk.NewScrollBar(mw, tk.Vertical, tk.WidgetAttrInitUseTheme(false))
vertScrollbar.SetNativeAttribute("command", "canvas yview") // bad window pathname error
tk.Grid(canvas, tk.GridAttrRow(0), tk.GridAttrColumn(0), tk.GridAttrSticky(tk.StickyAll))
tk.Grid(frame, tk.GridAttrRow(0), tk.GridAttrColumn(0), tk.GridAttrPadx(15), tk.GridAttrPady(15))
tk.Grid(vertScrollbar, tk.GridAttrRow(0), tk.GridAttrColumn(1), tk.GridAttrSticky(tk.StickyNS))
return mw
}
func main() {
tk.MainLoop(func() {
mw := NewWindow()
mw.SetTitle("ATK Sample")
mw.Center(nil)
mw.ShowNormal()
mw.BindKeyEvent(func(e *tk.KeyEvent) {
if e.Event.KeyCode == 9 { // esc key
tk.Quit()
}
})
})
}
The problem is these Python/TKinter lines:
vsb = tk.Scrollbar(root, orient="vertical", command=canvas.yview)
canvas.configure(yscrollcommand=vsb.set)
frame.bind("", lambda event, canvas=canvas: onFrameConfigure(canvas))
`
Any help appreciated.
If the focus of the question feels too narrow then how about example code showing attaching a scrollbar to anything?
I'm sorry that my code isn't appropriately indented. I clicked the "<>" icon, copy/pasted and lost the indents.
